Web12 nov. 2024 · In order to improve the output velocity, the non-resonance low-harmonic driving waveform is adopted and compared with the classic saw-tooth driving waveform. Experimental results show that with the STW, the motor is capable of achieving a maximum output velocity of 0.73 mm/s at 800 Hz and a maximum driving frequency with valid … Web8 nov. 2024 · A set of chemical SAW sensors coated with parylene C layers of different thicknesses (1, 1.5, and 2 µm) and an uncoated sensor were used as test samples. The sensors represent dual-channel electroacoustic delay lines operating in the vicinity of 77 MHz. The IDTs consist of split aluminum electrodes deposited on a AT-cut quartz substrate.
